Love your bike? Love your back! Bikers have strong and tight quadriceps, psoas, and hamstrings. All that pedaling shortens these muscles and puts loads of downward pressure on the pelvis. The pelvis stays in a tucked position and drags the lower back down with it. This prolonged rounding is super unhealthy for the lower back, shoulders and neck, and leads to compression, strain, muscle knots, and bulging discs over time.
Yoga can help tremendously, but not if it's the fluffy kind. Learn how to practice yoga and move according to YOUR body type and flexibility level.
